What are the characteristics of suckling piglets? Pig farmers should understand this in advance

First, they grow and develop quickly and have vigorous material metabolism. Suckling piglets are still in the early stage of life. Their absolute growth (the absolute value of weight gain per unit time) is very small in intensity, but their relative growth (the multiple of weight gain within a certain period) is very great in intensity, and their plasticity is also great, so their feed conversion efficiency is very high. If growth and development are hindered at this time, they can easily become "runty pigs." Second, the various physiological functions of suckling piglets are immature, making them susceptible to various diseases and also easy to be crushed, frozen, or starved to death. The mortality rate of piglets after birth accounts for most of the mortality rate over the entire life span.
